Galderma Benzac AC Benzoyl Peroxide Gel 2.5% 30g

Ingredients

Galderma Benzac AC Gel contains 2.5% benzoyl peroxide as its active acne-treatment ingredient. The gel base also includes oil-absorbing, moisturizing, stabilizing and texture-supporting ingredients that help distribute the active ingredient evenly across the affected skin.

Benzoyl Peroxide 2.5%

Benzoyl peroxide is the active ingredient responsible for the product’s acne-treatment action. It helps reduce Cutibacterium acnes, a bacterium associated with inflammatory acne, while providing mild keratolytic activity that helps clear blocked pores. This can support the management of pimples, blackheads and whiteheads.

The 2.5% concentration is commonly used as a lower starting strength. It may still cause dryness, redness, peeling or irritation, particularly during the first few weeks of use.

Acrylates Copolymer

Acrylates copolymer is used in the formula as oil-absorbing beads. According to Galderma, these beads help absorb excess surface oil while releasing glycerol. This delivery system supports a more comfortable application and may help reduce some of the dryness or irritation associated with benzoyl peroxide.

Glycerol

Glycerol, also known as glycerin, is a humectant that attracts and retains moisture. It helps balance the potentially drying effects of benzoyl peroxide and supports a softer, less tight skin feel. Glycerol does not treat acne directly but contributes to the overall comfort and tolerability of the formula.

Propylene Glycol

Propylene glycol functions as a solvent and humectant. It helps keep the formula evenly mixed and supports the distribution of other ingredients across the skin. It can also help reduce moisture loss, although people sensitive to propylene glycol may experience irritation.

Carbomer 940

Carbomer 940 is a gel-forming and thickening ingredient. It gives Benzac AC its smooth gel texture and helps keep the active and supporting ingredients evenly distributed. It also allows the product to spread in a controlled, thin layer without feeling excessively runny.

Poloxamer 182

Poloxamer 182 is a non-ionic surfactant and solubilizing ingredient. It helps different components of the formula combine evenly and supports consistent application. Its primary role is maintaining the stability and performance of the gel rather than treating acne directly.

Docusate Sodium

Docusate sodium functions as a surfactant and wetting agent. It helps the formula spread evenly over the affected skin and supports the uniform distribution of benzoyl peroxide throughout the gel base. It does not provide a separate acne-treatment benefit.

Disodium Edetate

Disodium edetate is a chelating and formula-stabilizing ingredient. It binds with trace metal ions that could otherwise affect the stability or performance of the product. This helps maintain the consistency and quality of the gel during storage.

Other Formula-Supporting Ingredients

• Silicon Dioxide: Helps absorb moisture or oil and supports the texture of the gel.
• Sodium Hydroxide: Used in a small amount to adjust and maintain the formula’s pH.
• Purified Water: Acts as the primary base and helps distribute the ingredients evenly.

Ingredient information is based on Galderma’s official Benzac AC consumer information. Regional formulations and package sizes may differ, so customers should check the complete ingredient list printed on the 30g packaging, especially if they have known allergies or sensitivities.

How to Use

Benzac AC 2.5% should be introduced gradually to help reduce dryness and irritation. Unless your doctor, pharmacist or product packaging provides different directions, follow these steps:

1. Wash your hands before applying the gel.
2. Clean the affected skin with a gentle facial cleanser and water. Pat the skin completely dry without rubbing.
3. Apply a thin film of Benzac AC 2.5% only to acne-affected areas. Avoid applying an unnecessarily thick layer because this will not produce faster results and may increase irritation.
4. During the first three days, apply it once daily and leave it on for approximately two hours. Wash it off with water, pat the skin dry and apply a lightweight, non-comedogenic moisturizer.
5. After three days, if no troublesome discomfort occurs, apply it in the evening and leave it on overnight.
6. After seven days, if there is no significant redness or peeling but improvement remains limited, the frequency may be increased according to the product label or the advice of a doctor or pharmacist.

How to Add Benzac AC 2.5% to Your Routine

Morning: Use a gentle cleanser, moisturizer and broad-spectrum sunscreen. Avoid excessive sun exposure while using benzoyl peroxide.

Evening: Cleanse the skin, allow it to dry and apply a thin layer of Benzac AC to the affected area. Follow with moisturizer when appropriate.

Benzac AC is for external use only. Avoid the eyes, lips, mouth, corners of the nose, sensitive neck areas and damaged skin. Do not combine it with retinoids, exfoliating acids or other topical acne treatments unless advised by a healthcare professional.

The gel may bleach hair, towels, pillowcases and coloured clothing, so allow it to dry completely and wash your hands after application. Stop using it and seek medical advice if severe swelling, blistering or an allergic reaction occurs.

Directions can vary between regional formulations. Always follow the instructions printed on the imported 30g packaging if they differ from the guidance above.

Highlights

Important: Benzac AC 2.5% may cause dryness, redness, peeling, stinging or irritation during the adjustment period. Avoid damaged skin and sensitive areas around the eyes, lips and mouth. Benzoyl peroxide can also bleach hair, towels, pillowcases and coloured clothing.
